Homework Assignment-1Topics: Functions, Dictionary, ImportProblem description: Write a python application to simulate an online clothing system. Thepurpose of this assignment is to gain experience in Python dictionary structure, create basicPython functions and import a module.Design solution: The template file contains a list of clothes item sold, each item in the listcontains the item id, name of the item and the prices. The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item. This program implements a dictionary called cart, where each key isthe item id and the values are the list of name, price and quantity that user chooses topurchase. The program keeps repeating by displaying the main menu to…
3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]

Define a Friend class , where each Friend object…
Using Classes Write a program that inputs, processes, and outputs a set of student records organized as a vector of class StudentRec objects. write a program where each student record is constructed using the class StudentRec. The variables in this case are "private" and the functions are "public." Note: only the first_name and last_name variables will require "getter" functions that return the name in all caps: get_first_name_upper() and get_last_name_upper() functions. Your class declaration section should look something like this: class StudentRec { private: string last_name = ""; // Last name string first_name = ""; // First name int year_grad = 0; // Year expected to graduate float gpa = 0.0; // Current gpa public: void set_last_name(string last_name_param); string get_last_name() const; string get_last_name_upper() const; // the rest of the "setter" and "getter" functions for each variable above go…
C++: You will create a header file with implementation that performs the task. Together with the header and implementation, you create a test program whose main function demonstrates that your functions work as they should. Two files, A and which they are sorted. The files contain Numbers. Based on the files, create a third file let calles it C . that file C is going to contain all the elements in sorted order from both files A and B. This operation is called a merge..
a C++ program to implement movie rent store, using Linked List, which will allow the store owner to perform the following functions: a) Insert the new Movie cassettes/CD record in store. b) Delete the record of the existing movie record by record id. c) Display available movie cassettes/CD record. d) Rent out movies cassettes/CD e) Display rented cassettes/CD records. Following details should be displayed against each record: Record Id,Name,Genre,Release Date,Movie Length,Production House,Rented Date
C++ Write a program that will allow a user to enter students into a database. The student information should include full name, student ID, GPA and status. The program should allow delete any student based on student ID. You may not use a vecto or an array only the list function.
Hi, I need help implementing this function into my code. This topic is about getting information out of text files: Function: get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary
Unique Words Summary Specifications:You are tasked to implement an abstract data type class which takes in a given input file called input.txt, and processes, identifies and sorts all unique word instances found in the file. Sample InputHi hello hi good bye goodbye Bye bye good say Sample OutputBye Hi bye hello hi say The input.txt file is found along with the zip folder where this instructions file also came along with. Note: you are not allowed to use pythonic lists, and its methods and functions, and string methods. However the use of the file handling methods (read readlines and readline) are allowed for this project.

In C++ data structure Please write program per instructions. Thank you A set is a collection of distinct elements of the same type. Design the class unorderedSetType, derived from the unorderedArrayListType, to manipulate sets. Note that you need to redefine only the f unctions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs and appropriate message. Also, write a program to test your class: then Redo the program using templates
